Influences of Shear Stress on Peristaltic Transport of a Non-Newtonian Fluid in a Micro Asymmetric Channel.

The movement of a Williamson fluid is studied in a micro asymmetric walls and it is initiated by the movement of peristalsis waves with the constant speed, however with distinct amplitudes and phase on the stretchy walls under LWL wavelength and LRN assumption. The perturbation method in the power of We is constructed to get explicit forms for velocity, pressure rise, frictional forces and shear stress. The properties of several developing parameters on the fluid motion are presented graphically. In addition, the streamlines prototype is designed and it is examined that trapping happens near the walls and the magnitude of the trapped bolus varies with changing inserted flow parameters.
